Spiralized Summer Squash Casserole with Gluten-Free Breadcrumbs

Happy August!

There are two types of recipes that I get requests for the most. First, it’s “easy, quick weeknight recipes” and second, it’s “dishes I can bring to a potluck.”

This recipe satisfies the second request! If you’re looking to bring a side dish to a BBQ or potluck or even just want to make something easy to share, this casserole is it!

It’s almost like a gratin, and the little chip slices are made with the Inspiralizer. You can see how to do that exactly, here.

I used yellow squash and zucchini to make this gratin, to truly use up all of that summer squash! The squash cooks and softens, releasing a bit of moisture into the casserole dish, making a warm sauce once it melts with the Parmesan cheese.

The gluten-free breadcrumbs are really the star of the show here. If you haven’t made them yet, let this be your inspiration. I even have a video on how to make them! They save well in the fridge, too – so you can totally make a big batch and use them all week.

Now, onto other matters. It’s officially August!

Starting today, I’ll be posting only three times a week, instead of four times a week. I’m decreasing the posts and preparing the next few months for my leave. I’ll be posting Sunday, Monday, and Wednesdays!

You can also find new posts on inspiralizedali (I post twice a week there), if you’re looking for some more lifestyle content.

Thanks for your understanding, as always!

Save RecipeSave Recipe


  • 2 medium zucchini
  • 2 medium yellow squash
  • 3 tablespoons extra virgin olive oil
  • salt and pepper
  • 2 tablespoons grated Parmesan cheese
  • For the breadcrumbs:
  • 2 tablespoons almond meal
  • 1/8 teaspoon dried oregano flakes
  • 1/8 teaspoon dried basil flakes
  • 1/8 teaspoon dried parsley flakes
  • 1/8 teaspoon garlic powder
  • salt and pepper, to taste
  • 1 teaspoon water


  1. Preheat the oven to 350 degrees.
  2. Place a medium skillet over medium heat and coat with cooking spray. Meanwhile, in a small bowl, combine all of the ingredients but the water for the breadcrumbs and mix together. Add in the water and use your hands to form a dough – it should end up in a ball. Crumble the dough ball into the heated skillet and continually break up with a wooden spoon. Cook for 2-3 minutes or until breadcrumbs break up, harden and become “toasted.” Set aside in a bowl.
  3. Slice the zucchinis and yellow squashes halfway through lengthwise, careful not to pierce through the center. Spiralize on Blade A to yield chip-slices.
  4. Grease a baking dish with cooking spray. Lay the zucchini in an even layer. Top with yellow squash. Top with zucchini. Top with yellow squash. Then, top with zucchini. Keep going until all your squash is used. Sprinkle over with the prepared breadcrumbs. Drizzle over with olive oil and season with salt and pepper.
  5. Cover the dish with foil and bake in the oven for 30 minutes. Remove the foil and immediately sprinkle with Parmesan cheese. Serve.

Hi! Looks Devine! Is the recipe supposed to have Parmesan cheese in it? You say the squash melts with the Parmesan to make a sauce, but I don't see it listed anywhere else in the recipe. Thanks!!!

I made this for dinner tonight with a pound of Italian sausage and a tablespoon of fennel seeds. It was excellent! My whole family loved it. Will make again. Great way to enjoy all that beautiful zucchini in our garden with a nice Italian flair! Thanks for the recipe!

my 2020 holiday gift guide is finally live on the blog! 🎁 you’ll find my picks For Her (like this cute velvet puffer!), For Him, For Toddlers, and Under $50. but let me leave this disclaimer here: it’s the thought that counts. gift giving is supposed to spread joy - don’t get caught up searching the internet for hours for the “perfect gift.” the perfect gift is simply something thoughtful 💓 and frankly, our good health is the best gift we could all ask for this year 🖤 but if you need some more inspiration, check out my stories for swipe ups or go straight to Inspiralized.com! 😘 #holidaygiftideas #holidaygiftguide ...

a festive seasonal snack or dessert idea for you and your little ones 🍎 - these french toast apple slices were inspired by my grandmother and this apple butter, cinnamon, maple syrup toast situation she used to make with her famous applesauce. you can grab this recipe from #inspiralizedandbeyond! ⁣

tell me how everyone's doing on their thanksgiving prep - ready? haven't even started yet? I haven't bought a single thing yet! 😇😱🤡

the holidays are going to be very tough and emotional for many of us this year. we're not going to spend it with the loved ones we typically do to keep one another safe and even worse, some of us will miss family we've lost to the COVID virus. 💔⁣

something that always cheers me up is food. I've come to realize that one of the reasons it has this therapeutic effect on me is because it's a safe space for me to block out everything else and just enjoy the art of cooking. 🥄⁣

and I realize that this will not be helpful to everyone ("oh, ali, I can't just cook it all way!"), but if it does, try to get in the kitchen and cook (or bake!) something that brings you happiness. and if it does not and you're sad right now, that's okay too. it's okay to not feel okay. 🙏🏼 I wish I could help more, but in the meantime, my love, strength, and heart goes out to you. I'm thinking of you.⁣

but, IF food and cooking is cathartic for you too, I encourage you to make something new this year for Thanksgiving (or over whatever holiday you celebrate.) sometimes following steps in a new recipe keeps your brain focused on the task and you're able to let everything else wash away. at least that's how it is for me! I'm flipping through my cookbooks and sharing some of my favorite holiday-friendly recipes over on stories, like this one from #InspiralizedandBeyond! 📚⁣


makes 8-10 crostini⁣

1 large golden beet (about 6 ounces), peeled and sliced into 1/8" thick rounds⁣
1/4 cup ricotta cheese⁣
5 fresh figs, diced⁣
honey, for drizzling⁣

arrange the beet slices on a serving platter and spread about 1 teaspoon of the ricotta on each. top evenly with the chopped figs and drizzle very lightly with honey. serve.
